SAT January 2012 - Math

<p>was another answer about money made each week 46w…i dont think anyone has mentioned that</p>

<p>@SAT I got 46w for that as well. It was like 25(w) + (7)(3)(w) if I remember correctly.</p>

<p>Yeah I remember putting down 46w for one of the questions</p>

<p>What about the radius and the coordinate?</p>

<p>Can someone post a list of compiled answers?</p>

<p>I forgot to cancel the 2/2 in the semicircles question. Also thought that the x + y + z, x - y - z asked for what x equaled so I put 350…</p>

<p>do you guys want me to put together a list of answers?</p>

<p>@amphear what do you mean cancel the 2/2?</p>

<p>here’s some stuff…
There are 4 Combinations for the ones like DACEB.
For the Deer eating thing, it was"If the deer ate the flowers the dog was there in the yard."
For the magazine one, 7 people read both.
For the end most point number line, I put d has to be atleast 8.
I put perimeter is 44
Midpoint on parable x coordinate I put 3/2
2 digit numbers made from 1,2,3,4,5 answer was 20 I think
For the water tank, I put 8/3 as the new height.
For the 12^12 problem, I put “the 144th term.”
For the 2 semicircles I put (j+k)*pi
for the price of apples I put c(n+5)/n ( I think )
Protein and grams one I put 1700</p>

<p>The semicircles question was 150, right?</p>

<p>2 digit numbers made from 1,2,3,4,5 answer was 20 I think
i dont remember this one or the price of apples. Another question had prime numbers and then multiples of 3 and 5 below 20-this answer was 2 right?</p>

<p>@SAT it was 2. But did u get 150 for a grid-in answer?</p>

<p>i think so. what was the question?</p>

<p>i remember 130 as the grid in for the r+s+t but i dont recall 150</p>

<p>So does anyone remember the answer to the ice cream scoops question?</p>

<p>can someone please explain the perimeter question in the math grid in (the one with sides 10 and 12)? people have said its 44 but idk why…</p>

<p>@ SAT semicircles? I forgot.
EDIT: wait… no it couldn’t have been the semicircles. I really don’t remember, actually.</p>

<p>can somebody please explain why the two semicircle questions is (j+k)<em>pi rather than j</em>pi/2 + k*pi/2</p>

<p>@ sma719 because you plug in some numbers and get (j+k)pi.</p>

<p>Circumference of big circle was 2<em>pi</em>j, for the smaller circle it was 2<em>pi</em>k.</p>

<p>Because it wasn’t a full circumeference ( It was only half ), the circumeferences of both divided by 2, so pi<em>j + pi</em>k = pi(j+k)</p>
